Definitions

  • the invention relates to a molding process, in particular blow molding and / or vacuum molding process, for producing a dispensing container filled with a medium to be dispensed.
  • the invention is directed to the production of such dispensing containers, the main but not exclusive use of which is to introduce a desired volume of the medium, in particular a liquid medium in a receptacle.
  • the medium to be introduced is preferably an additive which, for example, is introduced as an active ingredient admixture into a fluid in the receptacle.
  • the receptacle can be an infusion container to whose contents the medium is to be added as an additional active ingredient.
  • a syringe As a dispensing container for this purpose usually a syringe is used, with the cannula a perforable closure or plug of the receptacle, such as the infusion container, is pierced, after which the medium is injected into the receptacle by expressing the syringe.
  • the preparatory step of filling the syringe is required by transferring the desired amount of the medium from a reservoir into the syringe or filling the syringe from a conventional vial containing the metered dose of the medium in question.
  • the integrated cannula and its protruding end, ie the needle tip, covering the safety device which covers the medium are combined to form an overall unit in the dispensing container produced by the method according to the invention.
  • the desired dose of the medium in question can be provided in the dispensing container before the dispensing operation . Since the needle tip is covered by the securing device, the container with secured cannula can be easily handled in its ready for the dispensing process state. Intermediate steps of transferring medium and preparing a syringe are not required for the dispensing operation. The desired simplification, time savings and increased security against contamination are thus achieved.
  • containers produced by the method according to the invention not only the risk of contamination of the medium is greatly reduced, but also reduces the risk that the user, such as a nurse injured, because the cannula is protected again after use by the securing device.
  • the securing means of the closure unit may be designed so that after removal of the protective cover of the cannula protection body when piercing the closure by conditioning at the same from its advanced protective position at the end of the cannula in the position of use can be pushed back and after pulling out of the cannula from the closure back into the protective position can be advanced.
  • the handling during the dispensing process is particularly simplified.
  • the steps of widening and filling the container in the mold are carried out jointly by means of a combined blowing filling mandrel which extends through the introduction opening. This allows a particularly efficient production of the filled containers with short cycle times.
  • the protective hood as an integrated part of the container and as part of the protective device is preferably formed when closing the head jaws of the mold in the region of the transition between the closure unit and protective cover on the wall of a predetermined breaking point, which forms a removal of the protective cover facilitating separation point.
  • At least one protruding handle piece is formed, which forms a twist-off knob for convenient manual separation of the protective hood.
  • an embodiment of a filled dispensing container produced by the method according to the invention is designated as a whole by 1.
  • it is an ampoule-like plastic container whose wall 2 is provided with folds and bellows-shaped, so that the dispensing container 1 can be compressed from the configuration shown in FIGS. 6 to 9, see FIGS Neck is inserted into the dispensing container 1 as an insert part closure unit 3.
  • the body 4 of the closure unit 3 is in the central region of FIG a cannula 11, the inner end 12 of which projects slightly inwardly over the body 4 of the closure unit 3.
  • the body 4 of the closure unit 3 also has a first component 17 of a cannula securing device extending along the projecting part of the cannula.
  • the second component of this securing device is a protective cover 5 surrounding the protruding part of the cannula 11, which is formed during the manufacture of the container 1 as an integral part thereof.
  • the invention is explained below using the example of a blow molding process.
  • the molding of the container with protective cover 5 could also be carried out by a vacuum molding process or a combined blow molding / vacuum molding process.
  • FIGS. 1 to 5 The sequence of the molding process is illustrated in FIGS. 1 to 5, in which the essential parts of a molding device are shown in greatly simplified schematic form.
  • the device comprises three pairs of movable mold jaws, namely main mold jaws 8 for forming the container to be dispensed receiving a main body, head jaws 10 for forming the closure unit 3 enclosing the upper container part, in the present example, the guard 5 of the securing device, and holding jaws 14 for stabilizing a
  • This is extruded from a nozzle 18, which in a conventional manner has a terminal 20 for the supply of supporting air in the fully open in Fig.
  • Fig. 3 shows that through the insertion opening 22 through which is formed by the severing of the tube 6, a movable, combined blowing filling mandrel 24 is retracted, through which the expansion of the tube 6 is effected by means of blown air, so that the container wall. 2 conforming to the walls of the main mold jaws 8 in a bellows-like configuration, and then, after the inside of the container has been shaped, the medium to be dispensed is filled in by means of the combined blow-filling mandrel 24, see FIG. 3.
  • the next step is the insertion of the closure unit 3 by means of a retractable through the insertion 22, movable suction pad 28, see Fig. 4.
  • the body 4 of the shutter unit 3 has a conical surface, which on a seat 27 abuts, which forms the inner wall of the tube 6 in the area in which the mold walls of the main mold jaws 8 adjacent to the head jaws 10.
  • Fig. 5 shows that further.
  • Course of the suction pads 28 is moved away after completion of loading process up and the mold is now closed by moving together the head jaws 10, whereby the extending in the region of the head jaws 10 section of the tube 6 is formed to the protective cover 5.
  • the head jaws 10 have a shaping projection 32 which upon closing of the head jaws 10 on the hose 6 forms an annular notch, which forms a predetermined breaking point 7, at which the protective cover 5 is to be separated easily from the rest of the container.
  • a rotary knob 9 is formed as a handle, which allows a comfortable manual twisting off of the protective hood 5.
  • the head jaws 10 have at diametrically opposite locations recesses to form two opposing rotary knob 9. Of these depressions, only in FIG. 4 is a recess 34 indicated by a dashed line.
  • the cannula 11 extends from the outer end of the body 4 of the closure unit 3 in a length which corresponds approximately to the length of a syringe cannula.
  • FIGS. 6 and 7 show operating states in which the protruding outer end 15 of the cannula 11 is covered by both components of the securing device, that is to say both by the protective cover 5 and by the component denoted by 17 as a whole.
  • This component 17 is integrally formed on the body 4 of the closure unit 3 and has an annular body 19 which is displaceable on the cannula 11 and in the protective position, see Figs. 7, 8 and 12, located at the outer end 15 of the cannula 11 to cover this cannula end, ie the needle tip.
  • the annular body 19 is integrally connected via integrally molded support members 21 rod-like shape with the body 4 of the closure unit 3, wherein the joints with ring body 19 and body 4 of the closure unit 3 in the manner of bending joints are yielding.
